| (54) | Bed access apparatus for invalids and handicapped |
| (57) Bed access apparatus comprising a pair of transverse base members (12) on which anchor
plates (20,22) are adjustably located and on which the bed (16) rests. Uprights (14)
extend upwards from the base members (12) and are joined by longitudinal overhead
bars (18). An outrigger bar (24) is attached to one or both overhead bars (18), extending
outwards transversely and downwards to a support post (26). |
[0001] The present invention relates to health care articles and in particular to apparatus used by patients for transfer into and out of bed.
[0002] A wide variety of bed mounted frameworks have previously been used as traction support frames on hospital beds, and as devices for transferring patients into and out of bed. However, even though a wide variety of designs for such apparatus have been developed, these apparatus are typically designed for hospital or institutional use and therefore are adapted to be used only with a hospital-type bed. Such structures must be secured to the bed frame in some fashion in order to utilize the frame itself as a supporting base. Typically, these apparatus include one or two horizontal bars that extend the length of the bed and are spaced above the mattress. These horizontal bars join with vertical posts that are either bolted to the headboard and footboard, or may be clamped or bolted onto the legs of the bed. As will be recognised, such attachments require that a particular style of bed frame be provided, normally a hospital-type bed with a tubular frame.
[0003] Most existing apparatus are therefore limited in the type or design of bed that the apparatus can be used with. Such conventional apparatus normally cannot be used with a typical household bed, which prevents the patient from using his or her own bed after the patient has left the hospital.
[0004] As previously noted, most conventional bed access or exercise apparatus include one or two horizontal bars that extend the length of the bed and are secured both at the head and foot ends of the bed. These overhead bars provide the patient with a handhold in order to shift himself toward the side of the bed, or may be used to perform various exercises while lying on the bed. To assist in the exercise function many other accessories can be secured to the overhead bars, such as a trapeze, straps or the like that provide a handhold that is easier for the patient to reach.
[0005] Such apparatus are generally satisfactory for exercise, traction and the like while the patient is on the bed. However, since the overhead bars are normally centred over the bed and spaced away from the bedside, these apparatus often do not provide sufficient assistance to the patient for getting into or out of the bed. This is particularly the case, for example, when a patient is wearing a cast or the like that immobilises both the hip and knee joints. Although the person can draw himself to the edge of the bed and swing his feet to the floor, no firm handhold is provided to allow the patient to pull himself upright to a standing position. The same is true for the reverse operation of getting into the bed.
[0006] Although some previous bed access devices have used an overhead cantilevered beam or the like that extends laterally to the overhead bars, such beams have normally been used as a track for mechanical lifting devices. These devices actually hoist the patient out of the bed and carry the patient to the bedside. Such devices have not provided an overhead bar that the patient can use himself in order to get into and out of bed. Further, since such devices provide a mechanical guide track that extends at the same height as the overhead bars, the lateral guide track is generally too low to provide a handhold alongside the bed which does not obstruct walking around the bed or the locating of a wheelchair alongside. If the lateral guide track is high enough so as to not obstruct the side of the bed, the bar would be too high to be reached by a person while lying on the bed.
[0007] For these reasons, many patients have been forced to rely upon either a mechanical device or another person to assist them into and out of bed, which often adds to the confined or dependent feelings they may be already experiencing due to their condition.
[0008] According to one aspect of the invention, there is provided apparatus for providing access to a bed comprising generally vertical uprights extending upwards from the head end of the bed and from the foot end of the bed and at least one overhead bar spanning the uprights to extend over the bed along its length, characterised in that the apparatus is free-standing and further comprises means defining a base for resting on a floor surface and for supporting the bed access apparatus the base including a head base member for location at the head of the bed and a foot base member for location at the foot of the bed to accommodate the bed therebetween, the uprights being connected to the head base member and the foot base member; and a head anchor plate secured to the head base member and a foot anchor plate secured to the foot base member, the head anchor plate and the foot anchor plate being arranged to rest on the floor surface and to support the bed, the head anchor plate and the foot anchor plate having a size and spacing therebetween to accommodate the floor supports of the bed whereby the bed access apparatus is stabilised by the bed resting thereon, so that additional securance to the bed frame is not required.
[0009] Preferably the apparatus also includes an outrigger bar coupled to at least one overhead bar the outrigger bar being vertically spaced above the overhead bar and extending generally laterally thereto; and an upright outrigger support post connected to the outrigger bar and resting on the floor to support outrigger bar and weight placed thereon.
[0010] According to this aspect of the invention therefore, the apparatus includes a framework having floor anchor plates secured to the framework base. The bed is seated on these anchor plates so that the structure uses the weight of the bed itself as a stabilising force, even though the structure is not clamped, bolted or otherwise secured directly to the bed.
[0011] According to another aspect of the invention, there is provided apparatus for providing access to a bed comprising generally vertical uprights extending upwards from the head end of the bed and from the foot end of the bed and at least one overhead bar spanning the uprights to extend over the bed along its length, characterised by: means defining a base for resting on the floor surface and for supporting the bed access apparatus thereon, in which the base comprises a head base member and a foot base member, the generally vertical head upright being secured at the head base and the generally vertical foot upright being secured at the foot base; a height spacing bar coupled to the overhead bar and an outrigger bar coupled to the overhead bar by the height spacing bar so that the outrigger bar is spaced above the overhead bar and extends generally laterally to the overhead bar.
[0012] Thus, according to another embodiment the bed provides at least one overhead bar that extends along the length of the bed at a height that is accessible to a person lying on the bed. An outrigger bar extends generally laterally to the overhead bar in order to extend out over the bedside. The outrigger bar is preferably raised above the overhead bar in order to provide a handhold for a person standing or seated in a wheelchair alongside the bed. Where the outrigger bar is raised, people are permitted to walk beneath the bar and the bedside is therefore not obstructed. Since the apparatus is a freestanding structure, the apparatus is adapted to use with a wide variety of beds.
[0013] Preferably the apparatus also includes an outrigger support post secured to the outrigger base the outrigger support post having a base resting on the supporting surface. Preferably, the apparatus also includes a head anchor plate secured to the head base member and a foot anchor plate secured to the foot base member, the head anchor plate and the foot anchor plate being arranged to rest on the floor surface and to support the bed, the head anchor plate and the foot anchor plate having a size and spacing therebetween to accommodate the floor supports of the bed whereby the bed access apparatus is stabilised by the bed resting thereon, so that additional securance to the bed frame is not required.
[0014] The present invention may therefore solve the problem associated with prior art constructions by the provision of a bed access apparatus that can be adapted to a wide variety of beds, whether residential or hospital-type. The apparatus can provide a passive structure that the patient can use to move himself into and out of bed without requiring mechanical assistance.
[0015] Preferably, there are at least two head anchor plates and at least two foot anchor plates the spacing between the head anchor plates and between the foot anchor plates being adjustable, in order to accommodate beds of different sizes. Preferably there are at least two head uprights at least two foot uprights and at least two overhead bars the overhead bars extending between complementary ones of the head uprights and the foot uprights. Preferably, the head upright the foot upright and the outrigger support post are selectively height adjustable. The outrigger bar may be connected to both overhead bars.
[0016] Preferably, the head base member includes ahead floor runner and the foot base member includes a foot floor runner, the uprights being secured to the floor runners so as to be selectively adjustable therealong. Preferably, a pair of end spacing bars extend from a pair of uprights so as to extend away from the overhead bar and from a bed positioned within the apparatus, and a joining bar is secured between the end spacing bars.
[0017] Preferably, the outrigger bar and the outrigger support post is a first generally flat module selectively removable from the overhead bars and the overhead bars are a second set of generally flat modules selectively removable from the uprights so that the uprights and each of the head and foot base members form third and fourth generally flat modules, whereby the bed access apparatus selectively breaks down to generally flat modules for transportation and storage.
[0018] The invention preferably therefore extends to a freestanding bed access apparatus for use with a bed having floor supports thereon that support the bed on a supporting floor surface, comprising: a head floor runner and foot floor runner, said floor runners spaced so as to accommodate a bed therebetween; a pair of generally vertical head uprights extending upwardly . from said head floor runner and a pair of generally vertical foot uprights extending upwardly from said foot floor runner, said uprights selectively adjustable along said floor runners; a pair of overhead bars spanning between said uprights so as to extend above a bed located between said floor runners; a pair of head anchor plates secured to said head floor runner so as to be selectively adjustably positioned thereon, and a pair of foot anchor plates secured to said foot floor runner so as to be selectively, adjustably positioned thereon, said anchor plates having a size and spacing to accommodate the floor supports of a bed thereon; an outrigger bar coupled to at least one of said overhead bars so as to extend generally laterally to said overhead bars, said outrigger bar spaced above said overhead bars; and an outrigger support post connected to said outrigger bar and spaced from said overhead bars for resting on the floor and supporting said outrigger and weight placed thereon.
[0019] The present invention provides an apparatus that can be used both in an institutional and home setting. A patient can thus use his own bed in order to provide more comfortable surroundings. Further, the apparatus permits the patient to transfer himself into and out of bed without mechanical assistance and often without assistance from another person. The structure is not generally institutional in appearance and therefore does not detract from a residential environment to the degree of other such devices. Also, the structure breaks down into generally flat modules for transportation and storage.

[0021] A first preferred embodiment of the bed access apparatus is shown in Figure 1 under reference numeral
10. The apparatus includes a pair of spaced transverse base or floor runners 12, from which extend a set of generally vertical uprights 14 at both ends of a bed
16. Corresponding uprights 14 are joined by a pair of parallel overhead bars 18 that extend the length of bed
16. A pair of head anchor plates 20 are coupled to one base runner 12 so as to be slidably adjustable along its length, while another pair of foot anchor plates 22 are coupled to the opposite base runner 12 so as to be slidably adjustable along its length. The bed 16 rests upon the anchor plates 20 and 22 so as to stabilise the apparatus 10, without being otherwise directly connected thereto. An outrigger bar 24 is coupled to one overhead bar 18 so as to extend generally horizontally and laterally thereto. At the outboard end of outrigger bar 24 is an outrigger support post 26 that rests upon the floor surface so that the apparatus 10 is a free standing unit. The outrigger bar 24 is spaced above the overhead bars 18 and thereby provides a raised handhold alongside the bed 16.
[0022] As shown in Figure 1, the base runners 12 are hollow rectangular tubes, preferably 58 inches (1.47m) long, that extend along the supporting floor surface. One base runner 12 extends along the head end 30 of the bed 16 while the other extends along the foot 32 of the bed 16. The floor runners 12 are spaced sufficiently to accommodate a full size bed between them.
[0023] One head anchor plate 20 is shown in greater detail in Figure 4. The other head anchor plate 20 is a mirror image thereof. The head anchor plate 20 includes a flat plate or platform 40 that extends from the runner 12 towards the bed 16 along the supporting floor surface. The platform 40 extends from a short rectangular collar 42 that is slidably received over the base runner 12. The collar 42 slides along the length of the floor runner 12 so as to adjust the spacing of the head anchor plates 20 to correspond to the particular width of the bed 16. A pair of hand tightened clamp bolts 44 protrude through the upper surface of the collar 40. The bolts 44 lock the collar 42 in place on the floor runner 12.
[0024] When the floor anchor plate 20 is positioned on the rail 12, the support leg for the bed 16 rests on the platform 40 in order to provide a stable base for the apparatus 10. A sidewall or lip 46 protrudes upwardly along the outer side of the platform 40 in order to abut the supporting leg of the bed 16. The sidewalls 46 of the head anchor plates 20 co-operate to prevent the floor runner 20 from shifting sideways and thus prevent the head anchor plates 20 from sliding out from beneath of the legs of the bed 16.
[0025] One foot anchor plate 22 is shown in greater detail in Figure 5. The other foot anchor plate 22 is identical thereto. The foot anchor plate 22 is similar to the head anchor plate 20, in that the foot anchor plate 22 includes a floor platform 50 that extends along the floor surface towards the bed 16 from a collar 52. The collar 52 is slidably received over the base runner 12. A pair of clamp bolts 54 are threaded through the collar 52 in order to lock the foot anchor plate 20 in the selected position along the length of the base runner 12. The anchor plates 22 differ from the anchor plates 20 in the provision of an end wall or lip 56 that protrudes upwards from the floor platform 50 parallel to the base runner 12. The end walls 56 are positioned adjacent the support legs for bed 16 and also assist in preventing the support legs from sliding off the foot anchor plates 22.
[0026] The uprights 14 at each end of the bed 16 include a pair of spaced lower sections 60 joined by a crossbar 62 that is welded between the upper ends of the sections 60 to form a unit. An upper section 64 is telescopically received in each lower section 60. Connecting bars 18 span between corresponding upper sections 64 at the head and foot of apparatus 10, in order to provide a pair of parallel overhead bars that extend the length of bed 16.
[0027] The lower sections 60 of the uprights 14 are each welded to a rectangular collar 66 (Figure 6), and the joint is reinforced by a gusset 67. The collars 66 are slidingly received over the base runners 12 in order to be slidably adjustable along the length of the runners 12. A hand tightened clamping bolt 68 is threaded through the upper surface of each collar 66 in order to provide a locking or clamping adjustment between the collar 66 and the runner 12.
[0028] The uprights 14 can therefore be slid along the length of the runners 12 between the anchor plates 20 and 22.
[0029] The lower sections 60 and the upper sections 64 of each upright 14 include complementary vertical adjustment apertures 70 that align to receive a vertical adjustment pin 72. The height of the upright 14 can thus be adjusted in order to accommodate beds 16 different heights and also to accommodate different arm lengths of patients using the apparatus 10. The uprights 14 preferably have an overall height of 58 inches (1.47m) with a 7 inch (17.8mm) telescoping overlap between the lower sections 60 and the upper sections 64. The relative height of the lower section 60 to the upper section 64 may be varied, but is preferable that the lower section 60 is greater in length in order to position the crosspiece 62 towards the supper end of the uprights 14 for greater stability.
[0030] As shown in Figure 1, the overhead bars 18 are generally horizontal, tubular bars and each include two sections 80 and 82 to allow the overhead bars 18 to take up different lengths. The section 82 includes a smaller diameter adjustment post or bar 84 that projects from one end and is telescopically received in the section 80. A bolt or pin passes through the section 80 and the adjustment post 84 in order to lock the sections 80 and 82 together. Alternatively, the section 82 can have a smaller diameter so as to be telescopically received in the section 80, with a bolt or locking pin securing the sections 80 and 82 together. Overhead bars 18 of varying lengths can thus be used depending upon the length of the bed 16.
[0031] The outrigger bar 24 includes a height spacer bar 90 that extends generally vertically upwardly from one of the overhead bars 18. At the lower end of the spacer bar 90 there is a clamp 92 that shown in Figure 7 in greater detail. The clamp 92 includes a fixed plate 94 that is welded to the spacer bar 90, and includes a semi-circular channel 96 that accommodates the overhead bar 18. A separable clamp plate 98 is configured similarly to fixed plate 94. The fixed plate 94 and clamp plate 96 are bolted together by bolts 99 in order to clamp over the overhead bar 18. The spacer bar 90 is preferably 17 inches (0.43m) high, but other vertical spacings could be provided. An alternative coupling for the outrigger bar 24 is shown in phantom in Figure 1, connected to both the overhead bars 18. The outrigger bar 24 extends over both the overhead bars 18, and another spacer bar 91 extends upwards from a clamp 92. The outrigger bar 24 could alternatively angle downwards to the second overhead bar 18. The outrigger bar 24 is preferably 42 inches (1.07m) long, so as to provide this spacing between the support post 26 and the overhead bar 18 and to permit the positioning of a wheelchair alongside the bed 16.
[0032] The support post 26 includes a lower section 100 and a telescoping upper section 102. The upper section 102 is connected to the outboard end of the outrigger bar 24. Both the lower section 100 and the upper section 102 have complementary vertical adjustment apertures that align and receive a lock pin 106. The height of the support post 26 is therefore adjustable along with the adjustment of the uprights 14. At the base of the lower section 100 there is a base plate or platform 108 that rests upon the supporting floor surface. The support post 26 is preferably 75 inches (1.91m) overall with a 7 inch (17.8mm) overlap between the lower section 100 and the upper section 102.
[0033] Alternatively, the height spacer bar 90 can also have a telescoping height adjustment (not shown) in order to permit the spacing between the outrigger bar 24 and the overhead bar 18 to be adjusted.
[0034] The apparatus 10 can be disassembled for transportation or storage into generally flat modules. For such disassembly, the clamp 92 is disconnected so that the outrigger 24 and the support post 26 form a generally flat module. The overhead bars 18 with the upright upper sections 64 attached are removed also to form generally flat modules. When the anchor plates 20 and 22 are removed from the floor runners 12, the upright lower sections 60 and the floor runners 12 form a pair of generally flat modules. The various modules can then be stacked and stored in a very compact condition.
[0035] In use, a patient can pull himself to a seated position on the bed by grasping the parallel bars 18 overhead and shifting himself to the edge of the bed. After his legs are swung down onto the floor the patient can grasp the outrigger bar 24 and pull himself fully erect without obstruction from the outrigger bar 24. The apparatus can be used in similar fashion by the patient to transfer himself into a wheelchair positioned between the bed 16 and the support post 26, with the reverse process being used to get into the bed 16. The outrigger bar 24 and the overhead b.rs 18 may also be used for a variety of exercises in addition to assisting the patient in getting into and out of bed.
[0036] The apparatus 210 shown in Figures 8 and 9 is identical to the apparatus 10 described above, with the exception of the features noted below. Similar elements have therefore been given complementary reference numerals with a 200 prefix. The apparatus 210 therefore includes floor runners 212, uprights 214, overhead bars 218, anchor plates 220 and 222, an outrigger bar 224 and support posts 226.
[0037] As shown in Figure 8, the apparatus 210 includes an end access assembly that is located at the foot end 32 of the bed 16. Upright upper sections 264 extend upwards past the overhead bars 218. An end access bar assembly 274 is telescopically received in the upper ends of the upper sections 264. The end access assembly 274 includes end height spacer bars 275 which each include a depending post 276 that slide into the uprights 264. A pair of end spacing bars 278, which extend parallel to the overhead bars 218, project pass the end of the bed 16. A joining bar 280 connects the outboard ends of the end spacing bars 278 to provide a handhold therebetween. A patient can thus use the joining bar 280 to enter or leave the bed 16 at the foot end of the bed.
